This invention relates to improvements in combined. bath tubs and water heaters.

The general object oct the invention. is te provide a receptacle having means built V'therein for heating water contained in 'the receptacle.`

Another object of the invention is te provide a receptacle having` a novel electric or gas heating means built therein. i v

Other objects and the advantages oi .this invention will be apparent troni the following description taken in connection with the accompanying drawing wherein:

Fig. 1 is a perspective view et a` bath tub embodying the features oit' my invention.

Fig. 2 is an enlarged cross section. et the bath tub.

Fig. 3 is an enlarged section taken en line 8-8 et Fig. 2.

Fig. a is a side view of abath tub rinbodying a modiiied form et heater.

Fig. 5 is a section taken on line 5%5 et Fig. 4f, and Y Fig. 6 is an enlarged section taken on hn Referring to the drawing by reference characters I have indicated a bath tub einbedying the features of my invention generally at 10. Although in the accompanying drawing I have shown my invention in connection with a bat-h tub I wish it to be understood that it may be used in connection with various other receptacles with equal success.

The bath tub 10 may be of any type or shape including side walls 12. Adjacent the bottom of each of the side walls 12 I pro vide an outwardly extending portion 14 hav' ing end walls 15 which form a chamber 16 on the inside of the tub. Each o1 the end walls 15 of each portion 14C is provided with a screw threaded aperture 17 in which similarly screw threaded ends of a pipe 18 are positioned and retained in place by nuts 1Q which engage the threads on the pipe and bear against packing washers 2O interposed between the tub ends and the nuts.

Within the pipe 18 I position an electrical. heating element 21. As shown this heating element comprises a body portion 22 which may be made of vulcanized fibre or other` material. which is a non-conductor of electricity. In this body coiled resistance wires 23 are moulded. At one end of the elen ment 21 the wires 23 are connected to a plug socket 2tlwhich. extends out through one end et the pipe 18 and is adapted to receive the prongs el? a connector plug 25 connected by a cable 26 to an electric outlet fixture 27 as shown in Fig. 1. The end of the pipe 18 opposite the plug socket 2%1 is preferably closed in any suitable manner as by a screw threaded pipe plug 28.

lili/Then it is desired to heat a tub of water the water run in until the water level above the chanibers 1G and then the electric current is switched on to heat the elements 21 which in. turn heat the pipes 18 and thence the water in the tub.

In Figs. 5 and 6 I have shown one ar rangement wherein a duid burner is adapted.

. to heat the pipe 18 and thence the water in the tub. Various types of fluid `burners may be used but in the accompanying drawing I have shown a gas `luiriner 30. shown' the burner 30 comprises a ilaine pipe 31 having a plurality et apertures therein and closed at one end as by a pipe cap 33; rlhe opposite end of the pipe 31 engages a mixing valve 3a having` a shut eli' valve 35 connected thereto to which a gas hose 36 is attached.

The llame pipe 31 is adapted to be supported in the pipe 18 by a spider 37 secured to the pipe 31 and by a hub 38 on the mixing valve 34. The spider 37 and the mixing valve hub 38 are adapted te be movable in the pipe 18 se that when it is desired to light the burner the burner is moved out of the end of the pipe 18 a short distance, the gas turned on and ignited and the burner moved bach to position within the pipe 18.

The end of the pipe 18 opposite the miX- ing valve 3ainstead of being closed by the pipe plug` 28 as in the case of the electrical heater, has a pipe 40 connected thereto which is inclined downwardly towards the tub drain 4.1 and connected to the drain as shown in Figs. 4. and 5, thus affording a cireulation et air for the burning gas.

Instead et connecting the pipes L10 to the drain pipe 11 they may be connected to a chimney or any other suitable vent.

Frein the foregoing description it will be apparent that I have provided a novel water heater' which is simple in construction, durable, and highly eliicient in use.

Having described my invention, I claim:

LA. bath tub including side walls and having a chamber inone of said side walls, a heating member `in said chamber and means to heat said heating member.

' 2. The combination of a receptacle including a `side wall having a chamber open to the interior of said receptacle, a pipe secured in said chamber and a fluid heating element associated with said pipe.

3. The combination of a receptacle including a side wall, an outwardly extending portion in said side wall, said outwardly extending portion forming a chamber open to the interior of' said receptacle, a pipe arranged in said outwardly extending portion and a heating member arranged in said pipe.

4. In combination with a receptacle including side walls, an outwardly extending i portion in opposite side walls, said outwardly extending portions forming chambers open to the interior of said receptacle, a pipe removably secured in each of said outwardly extending portions and a fluid heating element associated with each of said pipes.

5. In combination with a liquid container including side walls and having a drain leading therefrom, an outwardly extending portion in opposite side walls, said outward- -ly extending portions p forming chambers open to the interior of said container, a pipe removably secured in each of said outwardly extending portions, fluid burning heaters, said heaters each being associated with one p of first mentioned pipes and one end of each of first `mentioned pipes having a conduit connected thereto and communicating with said drain.

6. In combination with a liquid container including sideY walls and having adrain leading therefrom, an outwardly extending portion in one of said side walls, said outwardly extending portion forming a chamber open to the interior of said container, a pipe removably secured in said outwardly extending portion, a'fluid burning heater associated therewith, said heater including a flame pipe, a mixing valve and a shut o' valve, said flame pipe being adapted to be positioned in first mentioned pipe and coaxial with first mentioned pipe, the end of first mentioned pipe opposite to mixing valve having a conduit connected thereto and communicating with said drain.

7. In combination with a liquid container including side walls and having a drain leading therefrom, an outwardly extending portion in opposite side walls, said outward- .ly extending portions forming chambers open to the interior of said container, a pipe removably secured in each of said outwardly extending portions, fluid burning heaters associated therewith, said heaters includin a flame pipe, a mixing valve and a shut-of valve, said flame pipes being positioned in first mentioned pipes, a spider on each flame pipe and a hub on each mixing valve adapted to support said flame pipe coaxial with one of first mentioned pipes, said spider and said hub being movable in first mentioned pipes and said hubs each being adapted to close one end of each of first mentioned pipes, the opposite ends of first mentioned pipes having a conduit connected thereto and communicating with said drain.

In testimony whereof, I hereunto affix my signature.

JOHN V. GARCIA.
